The proximity of the spinal cord to compressive metastatic lesions limits radiosurgical dosing. Open surgery is used create safe margins around prior stereotactic radiosurgery (SSRS) but carries risk potential surgical morbidity and interruption systemic oncological treatment. Spinal laser interstitial thermotherapy (SLITT) in conjunction with SSRS provides local control less a shorter interval resume authors present comparison between SLITT open patients thoracic epidural compression...
We report a rare case of primary synovial sarcoma the pericardium. Surgical resection was incomplete and chemotherapy radiotherapy (tomotherapy) were therefore administered. Regular cardiac magnetic resonance imaging scans used throughout follow-up, allowing effective planning application adjuvant therapies. The survival our patient 26 months, substantially longer than most previously reported cases.
The management of arteriovenous malformations (AVMs) the corpus callosum and choroidal fissure is challenging because they commonly receive arterial feeders from anterior posterior circulation, drain to deep veins. In this video authors present case a 20-year-old man who presented with acute onset headache, loss consciousness, nuchal rigidity. Computed tomography, MRI, cerebral angiography performed in tandem revealed ruptured, large, Grade IV AVM two groups feeders: one pericallosal artery...
The central sulcus region is an eloquent area situated between the frontal and parietal lobes. During neurosurgical procedures, it sometimes difficult to understand cortical anatomy of this region.Objective Find alternative ways anatomically navigate in during procedures.Method We analyzed eighty two human hemispheres using a surgical microscope completed review literature about region.Results In 68/82 hemispheres, did not reach posterior ramus lateral sulcus.
